NetBotz version 1
The following is the data sheet info on the ethernet chip set used on the version 1 appliances
LU3X31FT Single-Port 3 V 10/100 Ethernet Transceiver TX/FX
The LU3X31FT is an integrated 10/100 Mbits/s physical layer device with an integrated transceiver. This part was designed for 10/100 Mbits/s applications where board space, cost, and power are at a premium and stringent functional interoperability is a necessity. Operating at 3.3 V, the LU3X31FT is a powerful device for the forward migration of legacy 10 Mbits/s products and noncompliant (does not have auto negotiation) 100 Mbits/s devices. The LU3X31FT was designed from the beginning to conform fully with all pertinent specifications, from the ISO*/IEC 11801 and EIA/TIA 568 cabling guidelines to ANSI X3.263 TP-PMD to IEEE § 802.3 Ethernet specifications.
100 Mbits/s PLL, combined with the digital adaptive equalizer, robustly handles variations in rise-fall time, excessive attenuation due to channel loss, duty-cycle distortion, crosstalk, and baseline wander. Transmit rise-fall time manipulated to provide lower emissions, amplitude fully compatible for proper interoperability. Programmable scrambler seed for better FCC compliancy. Selectable CIM, Class II support, and powerful MII drivers for repeater applications.
IEEE 802.3u Clause 28 compliant auto-negotiation for full 10M and 100M control. Fully configurable via pins and management accesses. Extended management support with interrupt capabilities. PHY rise fall support. Symbol mode option. Full LED support. Low power consumption 150 mA max. 80-pin MQFP and 80-pin LQFP packages.
Single-chip integrated physical layer and transceiver for auto-negotiation-T and/or 100Base-T functions.
IEEE 802.3 compatible auto-negotiation-T and 100Base-T physical layer interface and ANSI X3.263 TP-PMD compatible transceiver.
PECL interface for external FX transceiver. Built-in analog 10 Mbits/s receive filter, removing the need for external filters. Built-in 10 Mbits/s transmit filter. 10 Mbits/s PLL exceeding tolerances for both preamble and data jitter.
